Abstract

A linear spring-loaded actuator (10) for a valve (12) comprises a housing (14) and an actuating spindle (16) slidably supported in the housing (14). A cap (22) is associated with the housing (14). Spring means (36), arranged in the housing (14), bear on the cap (22) and the actuating spindle (16), so as to exert a spring force on the actuating spindle (16). A thread (26) on the housing (14) cooperates with a thread (24', 24'') on the cap (22) for screwing the cap (22) on the housing (14) so as to preload the spring means (36) in the housing (14). At least one lock means (40) is associated with one of the threads (24', 24'') and is capable of deforming this thread (24, 24'') so as to lock it in any position on the cooperating thread (26).
